Abstract

Selon cette invention, un système de sécurité concernant la circulation routière peut être affilié à un objet pouvant être observé depuis une certaine distance et être localisé dans une zone de trafic. Le système de sécurité de la circulation routière peut comprendre un mécanisme rétroréfléchissant pouvant passer d'un mode réfléchissant à un mode non rétroréfléchissant à une certaine fréquence, ce qui permet de créer un effet de scintillement. Selon certains modes de mise en oeuvre, le mécanisme rétroréfléchissant peut être activé en mode par défaut normalement rétroréfléchissant. Le mode non réfléchissant peut comprendre un mode absorbant, un mode de transmission et/ou un mode de dispersion.
